Justin Olsen was recently interviewed by Stan Horaczek for PopPhoto.com. Olsen goes into detail about the custom mount he created to secure a DSLR to his chest. Oh, the other part? Olsen does some serious mountain bike activity, like flying through the air, as one of his Canon cameras clicks away.

Why not just use a helmet cam? Well, you couldn’t get images like this, for instance. With the camera lower on the shooter’s body, you get a different perspective than if it was atop a helmet. The action, and the bike in particular, seem a lot closer.

Olsen has a PocketWizard attached to his Canon in order to trigger the camera remotely. Check out his site for more extreme action shots. Great job, Justin!
